The wearables are also going to be 100+km away from each other. The button is clicked again that is attached to wearable A → an LED on wearable A turns off → the same LED on wearable B turns off. Something that if I can succeed in creating a prototype by myself I would be interested in working on a commercial/better version.Ī button is clicked attached to wearable A → an LED on wearable A turns on → an LED on wearable B turns on. That doesn’t mean I don’t want to solder stuff just if a suggestion requires an experienced solder it might be more hard for me.ĭue to confusion on why i’m asking this here is some context Perhaps I’m also missing other options?Īdditionally I have never actually soldered stuff before (I’m fairly new). Then i came across single modules like the ESP-WROOM-32 which seems very small but programming it seems more difficult than the other two options. What are your suggestions for the smallest BLE capable microcontroller? I came across the TinyPico and Beetle BLE which seem cool but I don’t know how easy programming these would be. I used an esp32 with the components being attached to a breadboard so that brings me to my questions. The bad news is that my tester microcontroller is way too big. I started out making sure the project was feasible and luckily I was able to figure it out. I am working on a wearable project that needs ble capabilities.
